Could someone possibly help me.
I have an aspx page that I need to produce Javascript on once a search is performed on data.
I have an ajax manager and have set the controls to update, however, I cannot get this routine on the server side to create the javascript on the page. If I do not use the ajax manager, it works fine.
This is the string that I need to write to the page (return), once a gridview updates.

    
            myStringScript = "<script type=""text/javascript"">" & vbCrLf & _  
        
                             "<!--" & vbCrLf & _  
        
                             String.Concat("var CheckBoxIDs =  new Array(", String.Join(",", ArrayValuesAttend.ToArray()), ");") & vbCrLf & _  
        
                             "// -->" & vbCrLf & _  
        
                             "</script>"

I have tried the following methods with no luck:

CheckBoxIDsArrayAttend.Text = myStringScript
(CheckBoxIDsArrayAttend is a literal control, and is also being updated by the ajax manager.)
-------------------------
TryCast(RadCodeBlock1.Controls(0), LiteralControl).Text = myStringScript
--------------------------
Page.ClientScript.RegisterStartupScript(Page.GetType(), "scr", myStringScript)

-------------------------------

None of these work. The Javascript just does not show up on the page after update (I can look for it when I view source on the page)
Any Ideas?
Thanks for your help.

Remove the ExpandCollapseColumn

Hi. I think I've tried everything, and I can't get rid of it. I want detail tables, but not the expandcollapsecolumn. This is what I have so far:

In the declaration:

    
            <MasterTableView> 
        
                ... 
        
                <ExpandCollapseColumn Visible="false" Display="false" /> 
        
                ... 
        
            </MasterTableView>

In code:

    
            protected void Roles_PreRender( object sender, EventArgs e ) 
        
            { 
        
                (RoleGrid.MasterTableView.GetColumn( "ExpandColumn" ) as GridExpandColumn).Visible = false; 
        
                RoleGrid.MasterTableView.Columns[0].Visible = false; 
        
            } 
        
            protected void RoleGrid_ItemCreated( object sender, GridItemEventArgs e ) 
        
            { 
        
                if( e.Item is GridDataItem ) 
        
                { 
        
                    (e.Item as GridDataItem)["ExpandColumn"].Visible = false; 
        
                } 
        
            }

With all this, I still end up with the ExpandColumn header showing up. The actual column cells are hidden, which causes all my other cells to be shifted left, thus getting their data in a row one left of their header... does it really have to be this hard to get rid of that thing?

[Solved] Q2 SP1 and Grouping

When we switched from Q1 to Q2 SP1 we lost the second group of a radgrid that had two groups - one that was not collapsed and one that was. We set the collapse in the code behind. Now the second group does not show up at all.

How to hide columns in a grid but show them during edit

My working environment is VS 2008, .Net 3.5, and RadControls for ASP .NET Q3 2007.

I have a grid displaying on my page. each record has 30 columns. I want the user to be able to edit these values in the edit popup box but I obviously don't want to try to display the grid w/ all 30 columns. Right now I am setting the visibility of the columns in the PreRender which hides the unwanted columns when the grid is not in edit mode and shows all the columns in the edit popup. Unfortunately, this also shows all the columns in the grid behind the edit window. Is there someway to specifiy that I only want to change the visibility of the edit windows columns instead of the MasterTableView?

Moving to previous or next record in RadGrid

I have a grid populated with data. The user can select a record and a second query populates data on a second tab page. The users need to be able to move forward and back in the main table data, while remaining on the second tab page. I need to have fields from the main table to pass to queries, so JS isn't the answer, so far as I know. I need a method to simply move the selection so that I can retrieve the new details.

The disappearing grid

Hi,

In my current project, one of the web pages displays a read only grid as follows:

                    <telerik:RadGrid ID="rgDetails" CssClass="CustomGrid" AllowSorting="true" AutoGenerateColumns="false" GridLines="Vertical" OnNeedDataSource="rgDetails_NeedDataSource" runat="server">         
                <ClientSettings>         
                    <Scrolling UseStaticHeaders="true" />         
                </ClientSettings>         
                <MasterTableView TableLayout="Fixed">         
                    <Columns>         
                        <telerik:GridBoundColumn DataField="EffectiveDate"      DataFormatString="{0:dd/MM/yyyy}" DataType="System.DateTime" HeaderText="Effective Date"      HeaderStyle-HorizontalAlign="Left" HeaderStyle-Width="10%" ItemStyle-HorizontalAlign="Left" UniqueName="EffectiveDate" />         
                        <telerik:GridBoundColumn DataField="Duid"                                                 DataType="System.String"   HeaderText="Duid"                HeaderStyle-HorizontalAlign="Left" HeaderStyle-Width="18%" ItemStyle-HorizontalAlign="Left" UniqueName="Duid" />         
                        <telerik:GridBoundColumn DataField="MaxCapacity"        DataFormatString="{0:N0}"         DataType="System.Int32"    HeaderText="Maximum Capacity"    HeaderStyle-HorizontalAlign="Left" HeaderStyle-Width="18%" ItemStyle-HorizontalAlign="Left" UniqueName="MaxCapacity" />         
                        <telerik:GridBoundColumn DataField="RegisteredCapacity" DataFormatString="{0:N0}"         DataType="System.Int32"    HeaderText="Registered Capacity" HeaderStyle-HorizontalAlign="Left" HeaderStyle-Width="18%" ItemStyle-HorizontalAlign="Left" UniqueName="RegisteredCapacity" />         
                        <telerik:GridBoundColumn DataField="GenunitCount"       DataFormatString="{0:N0}"         DataType="System.Int32"    HeaderText="Genunit Count"       HeaderStyle-HorizontalAlign="Left" HeaderStyle-Width="18%" ItemStyle-HorizontalAlign="Left" UniqueName="GenunitCount" />         
                        <telerik:GridBoundColumn DataField="WaterUtilisation"   DataFormatString="{0:N0}"         DataType="System.Int32"    HeaderText="Water Utilisation"   HeaderStyle-HorizontalAlign="Left" HeaderStyle-Width="18%" ItemStyle-HorizontalAlign="Left" UniqueName="WaterUtilisation" />         
                    </Columns>         
                </MasterTableView>         
            </telerik:RadGrid>        

The code behind is as follows:

                    protected void rgDetails_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)         
            {         
                this.rgDetails.DataSource = StationDeclaration.GelfStation.GelfStationDetails;         
            }         

The grid is displayed correctly initially as follows:

http://www.gouw.ws/RadGrid/BeforeBrowserResize.jpg

However, when the brower is resized the contents of the grid disappears as follows:

http://www.gouw.ws/RadGrid/AfterBrowserResize.jpg

I can't see what's happened with the code.

I have similar read only grids on the other web pages in the same application, but they don't have this problem.

Can you please help me?

Thanks & regards,

Herman Gouw

AllowMultiRowSelection is not working

Greetings,

I have a RadGrid that does not select multiple rows correctly when using the 'cntrl key.' The first row can be selected using the mouse and this action will highlight the entire row. However, when the next row is clicked by simultaneously holding the 'cntrl' key, only the * text * of this next row (or subsequent rows) will also be selected instead of the row.

There is a distinct difference between a row being selected/highlighted and the row's text being selected or highlighted.

Below is the code I have to declare the RadGrid. The most important property settings I could imagine are:

*  AllowMultiRowSelection="true"
* AllowRowSelect="True"

Outside of these two properties, is there something I am missing that keeps this from working right?

Thanks!

Did I do something wrong? My goal is to learn from this sample code and get to know the RadControl tool? FYI: I already have the telerik traniner 2.3.2.12 installed. However, I would like to see more complete project build installed of some part of the tool. I kinda what to know the whole package can offer with other professional works.

Thanks
